This paper presents an enhanced fault diagnosis method for identifying open-circuit faults in the switches of Three-Level Neutral Point Clamped (NPC) inverters integrated into Static Synchronous Series Compensator (SSSC) systems. Although previous studies have mainly focused on open switch faults in two-level convert...

Accurate and low-cost fault diagnosis is essential for improving the reliability of cascaded neutral-point-clamped (NPC) inverters. This paper proposes a single-sensor fault diagnosis method for a single-phase three-module cascaded NPC inverter. Only one DC-side current sensor is required for the diagnostic algorithm,...

In this paper, a fault diagnosis method based on temperature rise detection is proposed for power converters in switched reluctance motor drive systems used in electrical transportation equipment. First, the total power losses of all power devices are calculated and recorded under different operating conditions in both...

The insulated gate bipolar transistor (IGBT) is the core switching device in electric drive inverters. Its open-circuit faults pose a significant threat to system reliability due to their stealthy nature and potential to induce secondary failures. This paper proposes an intelligent IGBT open-circuit fault diagnosis met...

Low-voltage DC–DC converters (LDCs) require high availability to prevent critical vehicle accidents caused by abrupt voltage drops resulting from switch faults. Therefore, rapid fault detection and technologies that ensure safe operation during fault conditions are essential. This paper proposes a fault-leg identificat...
